Abstract
The millet head worm, the larval stage of the Noctuidae moth Raghuva albipunctella has become the most serious pest of millet in the Sudan. The adults emerge seven weeks after the first effective rainstorm of over 30 mm, which coincides with the heading of most millet varieties. The female lays eggs on newly emerged millet heads. Larvae enter the head and mine within the head, eating the bases of the flowers pushing up the severed florets in a characteristic spiral trace. Long‐maturing varieties and delayed planting are both effective in reducing the incidence of infestation but are impractical in the environmental conditions in Western Sudan. Varietal tolerance has been identified and should be used as one aspect of control. Synthetic pyrethroids reduce incidence but do not significantly increase yield. The use of triple superphosphate fertilizer increases yield and reduces the incidence of the head worm by reducing the time interval from planting to heading and resulting in the emergence of the main heads prior to the emergence of the pest
